SN74AVCH20T245GR TI Voltage Level Translator | 56-TSSOP | 20-bit, 2.3V-3.6V

Product Overview

The SN74AVCH20T245GR is a 20-bit (dual-supply) voltage-level translator from Texas Instruments, designed for bidirectional voltage translation between different voltage nodes in mixed-voltage systems. It operates with a VCCA range of 1.2V to 3.6V and VCCB range of 1.65V to 3.6V, making it suitable for interfacing low-voltage ASICs/FPGAs with higher-voltage peripherals. The device features automatic direction sensing, eliminating the need for direction control signals. Packaged in a 56-pin TSSOP, it offers high-speed operation with a typical propagation delay of 2.5 ns and low static power consumption.
